Polymarket API Error: the order signer address has to be the address of the API KEY

Hey, I have a (maybe) stupid question... I am trying to fill orders through API (Python if matters), and I keep bumping into this error.

I derived my private key freshly before trying and copied the deposit wallet address ("Address" in settings used for API) + confirmed its correct using the method described here for deposit wallet address: https://polynode.mintlify.app/guides/deposit-wallets

What am I doing wrong here?

I found this github issue which reproduces the same problem if anyone has any solution: https://github.com/Polymarket/py-clob-client-v2/issues/52
